DPiMS™ QT - Features

Kit for Direct Probe Ionization Mass Spectrometer

Simple pretreatment

Measure Liquid and Solid Samples with Simple Pretreatment

Simple Pretreatment
  • Reduces the time required to analyze blood, urine, and other biological samples with conventional methods by approximately 50 %.
  • Foods, tissue sections, and other solid samples can be analyzed as it. Pretreatment times are significantly reduced.

 

Note: Analytical precision can be improved even for solid samples by performing simple pretreatment such as dilution and centrifugation.

Rapid analysis

Speedy Qualitative Analysis

Speedy Qualitative Analysis

The qualitative analysis sequences for DPiMS QT and Q-TOF LC/MS were compared. Using DPiMS QT, it was possible to significantly reduce the measurement time in comparison to conventional methods using Q-TOF LC/MS.

Speedy Qualitative Analysis

Only a few dozen seconds are spent on DPiMS QT qualitative analysis. When performing qualitative screening analyses, the time before results are checked can be reduced, improving procedural efficiency.

Speedy Qualitative Analysis

High durability and stability

Analysis System with No Carryover

Only a few dozen pL of the sample adheres to the probe after each sampling. There is no worry of contamination inside the mass spectrometer. Carryover can even be prevented by changing probes. Concentrated samples and samples of unknown concentration can be measured.

Analysis System with No Carryover

Switching between DPiMS QT and Q-TOF LC/MS is Simple

Switching between DPiMS QT and Q-TOF LC/MS is Simple

Only about 15 seconds are required to remove the DPiMS QT unit, reconfiguring the system for Q-TOF LC/MS. The resources (solvents and columns) required for Q-TOF LC/MS analysis can be reduced by implementing qualitative analysis and primary screening via DPiMS QT, thereby reducing the number of samples requiring quantitative analysis.

Software

PESI MS Solution Software

PESI MS Solution software is used to control the probe, edit MS method files, and start measurements. Detailed MS analytical conditions are configured from the LabSolutions™ LCMS method editing window. Analysis can be started easily by selecting the probe control mode and MS method in PESI MS Solution. During analysis, the status can be confirmed in the LabSolutions LCMS window.

Sequence for Qualitative Analysis via MS and MS/MS

A qualitative analysis was performed on a whole blood sample mixed with trazodone (500 ng/mL). A cycle of MS and MS/MS measurements was performed simultaneously. LabSolutions Insight Explore was used for the data analysis. LabSolutions Insight Explore enables composition estimation, library searches, and structural analysis.
